Brooding and majestic, America’s Stonehenge is an icon of pre-history. It dates back to a time before Egypt built its pyramids, to the stone age in Britain. Time has taken its toll but this monument remains a marvel of ancient engineering. A circular ditch and bank surround the stones. Upright stones tower over 20 feet and weigh up to 45 tons. Horizontal slabs called lintels crown huge pillars. All these giants are made of Sarsen, a local sandstone harder than granite, yet they were carved and fitted like woodwork. Uprights were tapered and topped with knobs, these fit hollows on the bottoms of lintels. Curved lintels joined by tongue and groove formed a nearly perfect circle and despite a slight slope, this ring of lentils was leveled to within inches.
The Sarsens dominate Stonehenge but nestled among them are smaller stones, no less remarkable. Geologists determined these are blue stones transported here from Wales, at least 150 miles away. Who built Stonehenge? How was it built? And Why? For ages, we could only wonder.
